<p>Okay, I finished the Blue Book...wrote in it and everything, same with the Red Book...should I rebuy the Blue Book and go over the sections again? I did most of the Blue Book a while ago so it would look new to me, but idk if I should buy a brand new book or what?</p>
<p>There would be no use in rebuying the book. No matter how much you think you forgot about the tests, you will inevitably remember enough that it would be a waste of time the take them again to accurately gauge your progress. Just go through each section of the book, understanding why each answer is right/wrong. If you want more practice, the only real option is to buy the CB Online Course.</p>
